I've been reading all the instructions and whatnot in the list archives and it's all been very helpful.<br><br></div>I have the "top hats" removed, and the armatures out. I plan to order brushes and new gaskets from Harold.<br><br></div><div dir="ltr">The stupid little skinny screws that held the caps on the tall (3.5" dia) motors have sheared off in their holes. I'm thinking I will not bother drilling and tapping them back out, instead I will replace the motor through-bolts with stainless all-thread and extend them up into the caps, in the same way that the fat (4.5" dia) motor caps are held on. Has anyone else done this?<br><br></div><div dir="ltr">Everyone's recommending double rubber sealed bearings (2RS type) but those don't turn as freely as the original metal shielded bearings. Since I need all the "umph" I can get to mow my thick sedges and crabgrass, I hate the idea of using power-stealing bearings. Has anyone tried using bearings with rubber seals on only one side, and metal shields on the other (type RSZ)?<br><br></div><div dir="ltr">I have two motors where the commutator end bearing is pretty securely stuck in the brush holder assembly. Any tips on how to get them out?<br><br></div><div dir="ltr">Thanks!<br></div><div dir="ltr">--Charlie<br></div></div></div></body></html>
